Safety of the pressure-retaining equipment is a matter of cardinal significance in power plants. On-line monitoring of pressure-retaining equipment in power plants is a useful way to keep their safety. In the present research, some on-line fatigue monitoring systems that have been put into use in the plants are summarized, and the reason that possibly leading to accidents in plants has been analyzed. Moreover, the development of the structural integrity of the pressure-retaining equipment has been studied based on papers published in Engineering Village TM database during the recent 10 years. And the research subjects are statistically investigated and enumerated. According to the key research subjects, a new method of on-line damage monitoring of the pressure-retaining equipment is put forward. And the key technology problems in this new method are discussed.
